众所周知，氡在水中溶解良好，但这一过程的确切机制仍不清楚。因此，我们调查的氡的溶解度的相关性溶剂团簇。实验发现，在一定的乙醇含量下，乙醇-水溶液的溶解度会降低。用密度泛函方法计算了惰性气体原子在（H2O）20团簇中的包合比，并与实验结果进行了关联.结果表明，氡是水溶性的，由于封装在一个水簇。
Radon has been known to dissolve well in water although the exact mechanism of this process is still not clear. Thus we investigate a correlation of the solubility of radon to solvent clusters. We found experimentally that the solubility decreases in ethanol–water solutions at certain ethanol contents. Calculation of the clathration enthalpies for a noble gas atom confined in (H2O)20clusters were performed by using a DFT method to find a correlation between the theoretical enthalpies and experimental enthalpies of dissolution. It is suggested from the results that radon is water-soluble due to encapsulation in a water cluster.
